You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail. Thanks, Mark >From d790c342e689ea77a5cf72d5b993299911ee5276 Mon Sep 17 00:00:00 2001 From: Emil Renner Berthing Date: Wed, 31 Oct 2018 11:57:05 +0100 Subject: [PATCH] spi: rockchip: remove master pointer from dev data In almost all cases we already have a pointer to the spi master structure where we have the driver data. The only exceptions are the dma callbacks which are easily fixed by passing them the master and using spi_master_get_devdata to retrieve the driver data.
